FYI: I recently found that ceph performs quite well in vmware, when using the VM as a
"direct" ceph client.
(Our tests involved directly mounting an RBD device from the VM)
So as long as you can treat the OS level as throwaway, and use ceph-to-the-vm for your
actually important data, this might be also a good thing to use in ovirt.

Hi Matthew,
Currently, in order to use Ceph in oVirt you have 2 options:
1. Ceph using ISCSI gateway - regular ISCSI storage domain with Ceph as the storage
backend, supports all the regular operations [1].
2. Using the new Managed Block Storage (Cinderlib integration) technical-preview - Create
a Managed Block Storage domain that doesn't support all the operations that we have
for the "regular" storage domain you can find more info here [2] and [3].
Each option has its benefits.

Hi All,
I need some "best practice" advice. We have a Ceph Storage Cluster (Octopus
moving to Pacific) which we'd like to use with our new oVirt Cluster (all on CentOS 8
boxes). What I'd like to know is what is the "best" (ie recommended / best
practice) way of doing this - via iSCSI, CFS, 'raw' RBD blocks, some other way I
haven't read about yet, etc?
I realise 'best' is a subjective term, but what I tend to do is do
'manual' installs so that I both actually understand what is happening (ie how
things fit together - I pull apart and rebuild mechanical clocks and watches for the same
reason) and also so I can '"Puppet-ise" the results for future use. This
means that I am *not* necessarily looking for "quick and dirty" or "quick
and easy" (ie, I have no trouble using the CLI and 'vim-ing' conf files as
required) but I do want a solid, "best-practice" system when I'm done.
So, can some please help? And also, would you mind pointing me towards the relevant
documentation for the answer(s) supplied (yes, I *always* RTFM :-) ).
Thanks in advance
